THE family of a British gran beheaded by a maniac in Tenerife spoke of their grief ­yesterday, a year after the brutal murder.

Jennifer Mills-Westley’s daughters said they will never come to terms with the horrific way in which she was killed.

Crazed Deyan Deyanov attacked the 60-year-old with a ham knife, hacking her head off in a shop before running through the streets of a holiday resort with it in his hands.

Speaking for the first time about the attack, eldest ­daughter Sarah, 42, said: “I’m absolutely devastated by the loss of mum.

“She was my best friend and life will never be the same.

“It’s impossible to ­comprehend how viciously mum was killed.

“It’s only since mum’s ­murder that we have learned how ­mentally ill the killer was, how he moved from country to ­country wreaking havoc and the number of signs that, just ­perhaps, evidenced that he was capable of this type of offence.

“We have so many questions that are, as yet, unanswered.”

Deyanov, 28, the son of a Bulgarian millionaire who previously lived Edinburgh, was overpowered by a security guard in the resort of Los ­Cristianos and is being held in a secure psychiatric unit.

His defence lawyer claims he is unfit to stand trial.

Jennifer’s family released the statement to ­coincide with the anniversary of the killing today.
